LUTHER S. CHASE AN D ZEBIN A H. CHASE, OF NEW BEDFORD, MASSACHUSETTS; `SAID L. CHASE ASSIGNS HIS RIGHT TC Z. H. CHASE.

Letters Patent No. 88,008, dated March 23, 1869.

IMPROVEMENT IN vAfivEs FOR Bo'rToMs or vnssnns.

'Ime Schedule referred to in these Letters Patent and making part of the same.

* *-Qb-h* To all 'whom 'it may concern Be it known that we, LUTHER S. CHASE and ZEBINA H. CHASE, both of New Bedford, in the county of Bristol, and State of Massachusetts, have invented certain Improvements in Valves; and we hereby declare that the following is a full, clear, and exact description thereof, reference being hadto the accompanying drawings,

. in which- Figure l is a front elevation, showing valve closed. Figure 2 is a transverseseotional elevation through the centre. 1

Figure 3 is a front elevation, showing valve opened, and covering or protection removed.

Our invention is intended to be applied to the feed, or discharge-pipes of vessels, when the pipes lead to or from the sea; and-our object is to supply a want existing for the convenient and safe working of a valve, near the outside surface ofl vessels, from the inside.

Again, our invention may be applied for ventilators, and places for the admission of light in the sides of vessels. These places are new opened by swinginga cap, or

shutter upon a hinge outward, thus allowing an object to project from the vessel, which is objectionable.

In the pipes mentioned, a valve is now used, situated in the inside portion of the-pipes, which cannot be operated unless at the valves, and is liable to accident, while, our improved valve may be operated from any part of the vessel.

The idea of our invention was suggested by the recent accident to one of the steamers of the Bristol line, between Bristol, Rhode Island and New York, when it was necessary to beach the steamer.

The cause ofthe accident was a disarrangement of the valve in thefeed-pip'e from the sea, and it being impossible to reach the valve, on account of the water, the only way to prevent sinking was to beach the boat, which was d one. p

N ow, if our valve had been in use, it being operated from the engineers room, or even from the pilot-house, the water could have been shut oli" at once, and the necessity for beaching been avoided. f

As yet no means have been adopted to prevent the repetition of like accidents.

Our invention consists in a swinging valve, actuated by a shaft, the valve being situated on or near the outside of the vessel, a smooth surface being preserved on the outside.

In the drawings- A represents section of the outside of a vessel, outside presented to view.

B is a recess, cut into the side, in which the valve D swings.

C is a support, or shoulder, for the c to rest upon.

E is the feed, or discharge-pipe, and it may represent a ventilator-hole in theA vessels side.

F is the shaft which operates valve D. This shaft runs to the inside, and any power may be applied to it, for operating it, and the power may run to lany part of the vessel.

Ii, is an indicator, to show the position of the valve' The operation is readily understood.

By actuating shaft F, the valve is made to open or close, as necessity may require.

If the valve is used at the ventilator, a glass light is placed in it, to come into position, when thevalve is closed over the ventilator.

The use of this valve overcomes the objection of opening ventilators in the ordinary manner, that is, upon a hinge.

protecting cover The use of our valve for feed and discharge-pipesv does not interfere with the use of those in common use, and by using both, the safety 'of la vessel is 'increased, for, when one gives out, the other is ready for service.

In constructing our valve, the bearing, or shoulder C, maybe part of the vessel-side, o1" it may be sepaf4 rate, or a paitof cover B, or cover B may be dispensed with; but by using cover, or protection B, a more even surface is preserved on the outside.

Having thus fully described our invention,

What we claim as new, ters Patent, is The valve D, operating in recess R, in the side of a vessel, in combination =with shaft F, indicator fi, and pipe, or ventilator E, the whole constructed and arranged substautially as and for the purposes set forth and described.

A In testimony whereof, We have signed our names to this specification, in the presence of two subscribing witnesses.
